Take the following fragment of code
$ XPos = 0;
$ ZPos =0;
#while(ZPos<100)
#while(XPos<100)
blob {
threshold .65
sphere{<XPos,0,ZPos>, 1, 1
pigment{rgb<.25,1,.25>}
translate vturbulence (1.5, 3,
3,<XPos,0,ZPos>/33)
translate x*-50
}
}
#declare XPos = XPos + 1;
#end
#declare XPos = 0;
#declare ZPos = ZPos+1;
#end
How can I get all the blobs to bond together? I've tried putting the loop in
the blob statement but it seems to make no difference. I'm stumped, please
help

Your loops are making many separate 1-component blobs. You need to put
the entire looping structure that generates the components inside the
blob{} block.

Hmm...maybe your threshold and components are making it look like they
aren't blobbing together...do you get a bunch of intersecting spheres,
or are they completely disconnected?

Here's the code for a blob that has a while loop in it.
I hope it makes some sence to you and explains what you
need to know to solve your problem.
#local DogEar =
blob{
#local EarRot =0;
threshold 0.1
#while(EarRot <46)
sphere{<0,0.,0>, 0.125, 0.5 translate y*0.75 rotate
z*-EarRot}
#local EarRot = EarRot+2;
#end
sphere{<0,0.,0>, 0.15, 0.75 translate y*0.75}
texture{finish{ToyFinish}
pigment{TreeTrunckColour}
}
scale <1,1,0.45>
rotate z*-110
scale <2.5,2.5,2.75>
}

Hi Mick,
Happy New year!
As Chris says, you are creating a lot of seperate blobs. What you have to do is
have a single blob and have the loop within the blob. I did this when I was
trying to create smoke for one of my locos.
This seems to work OK;
$ XPos = 0;
$ ZPos =0;
blob {
threshold .65
#while(ZPos<100)
#while(XPos<100)
sphere{ <XPos,0,ZPos>, 1, 1
pigment{rgb<.25,1,.25>}
translate vturbulence (1.5, 3,3,<XPos,0,ZPos>/33)
translate x*-50
}
#declare XPos = XPos + 1;
#end
#declare XPos = 0;
#declare ZPos = ZPos+1;
#end
}

That's it
The threshold statement needed to be outside the while loop!
Thanks again

You are creating 10000 blobs with one component each instead of one
blob with 10000 components. The difference is quite clear.
See http://iki.fi/warp/PovVFAQ/whileloops.html for more details.
